Sherman Island: 2013-02-28 09:30:00 (DOY 59)
Author: Cove Sturtevant
Others: Laurie

Summary: Regular field work. Blew out in-line LGR filters. All A-OK.

Sherman
2013-02-28

We arrived about 09:30 PST. It was sunny and warm, 16 °C, with a steady breeze. No cows today.

I downloaded data, did general tower maintenance, and did spectral later while Laurie did moisture point, well depth, and soil respiration.

LGR readings: 8:44, 24.61 °C, 128.8 Torr (adjusted to 146.4 Torr), 13.876 us, 10 Hz, 1.86 ppm
I disconnected and blew out the two in-line filters in the tubing to the inlet. This resulted in no change to the readings.

7500 readings:
CO2: 17.0 mmol m-3
H2O: 460 mmol m-3
diag: 248
sos = 342 m s-1

MET looked good. I also cleaned the radiation instruments, which were pretty clean to begin with.
